Answer:

Constante de resorte, k = 19.745 N/m

Explanation:

<u>Dados los siguientes datos;</u>

Masa, m = 2 kg

Periodo, T = 2 segundos

Para encontrar la constante del resorte, k;

Period, \; T = 2 \pi \sqrt {\frac {m}{k}}

Dónde;

  • T es el período.
  • m es la masa del objeto.
  • k es la constante del resorte.

Haciendo k el tema de la fórmula, tenemos;

k = \frac {(2 \pi )^{2}m}{T^{2}}

Sustituyendo en la fórmula, tenemos;

k = \frac {(2 * 3.142)^{2} * 2}{2^{2}}

k = \frac {6.284^{2} * 2}{4}

k = \frac {39.49 * 2}{4}

k = \frac {78.98}{4}

<em>Constante de resorte, k = 19.745 N/m</em>

Having a skin that is pale, cold, and clammy are symptoms of heat exhaustion. Also, when your pulse is rapid, breathing is shallow are symptoms of such. One main cause of this would be being exposed to high temperatures especially when humidity is high and one is doing a physical activity. When no proper treatment, it could lead to heatstroke which may eventually cause death of the person. When one suspects that he is experiencing this, he should stop all that he is doing and rest. Then, he should move to place which has a cooler temperature. And drink fluids that are cold specifically water and sport drinks.

\large{ \boxed{ \bf{ \color{skyblue}{The \: correct \: question:}}}}

Q. In an ________ solution, red blood cells ________. Group of answer choices:

  • Hyposmotic, lose water and shrivel
  • Isomotic, have a normal shape ✔️
  • Isosmotic, swell and may burst
  • Hyperosmotic, have a normal shape
  • Isosmotic, lose water and shrivel

\large{ \boxed{ \bf{ \color{violet}{The \: correct \: answer:}}}}

In an <u>isosmotic</u> solution, red blood cells <u>have</u><u> </u><u>normal</u><u> </u><u>shape</u><u>.</u>

Option B

<h3><u>Explanation:-</u></h3>

Osmosis : The movement of the <u>solvent</u> or <u>water</u> molecules from a solution of their higher concentration to a solution of lower concentration through a <u>semipermeable membrane.</u>

❍ Depending upon the <u>osmotic concentration,</u> There are three types of solution and their result when cell is keot inside them:

  • Hyposmotic (Water enters, Swells up)
  • Isosmotic(Equal flow, No change)
  • Hyperosmotic(Water comes out, shrinkage)
